An ileostomy reversal is a procedure to reconnect the bowels. According to WebMD, an anastomosis, or reconnecting, of the portion of the bowel that was surgically attached to the exterior of the abdomen to the portion of the bowel that remains in the body is performed for this procedure. Ileostomies are done to ensure the body has a way to rid itself of waste.
WebMD describes that an incision is made around the stoma (the portion of the bowel that is surgically attached to the exterior of the abdomen). The next step in the procedure depends on which type of ileostomy procedure was originally completed. If a loop ileostomy had been performed originally, then the incision around the stoma would be the only incision needed. If an ileostomy that disconnected the ileum from the colon or other portions of the small intestine had been performed, then a larger incision to locate the small intestine or colon may be required. This reconnecting is only performed if the bowel appears healthy enough to return to typical elimination function, according to the National Health Service.
